Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to a press-fit fixture and assembly equipment. Background Technology

[0002] An atomizing device includes a liquid storage chamber, a liquid guiding component, and a heating element. The liquid storage chamber defines a storage cavity and an atomizing cavity. The storage cavity stores atomizing liquid and is connected to a replenishment bottle, which replenishes the atomizing liquid into the cavity. The liquid guiding component is disposed within the storage cavity and works with the replenishment bottle to conduct the atomizing liquid into the storage cavity. The storage cavity is in liquid guiding communication with the atomizing cavity. The heating element is disposed within the atomizing cavity to atomize the atomizing liquid flowing from the storage cavity to the atomizing cavity. During the production of this atomizing device, the liquid guiding component needs to be manually assembled into the storage cavity. This assembly method makes it difficult to ensure consistent assembly positions, and there is a potential problem of improper assembly of the liquid guiding component, affecting the replenishment rate from the replenishment bottle to the storage cavity, and thus affecting the normal operation of the atomizing device. Utility Model Content

[0003] This application provides a press-fitting fixture and assembly equipment for assisting in the assembly of liquid guide tubes, and solves problems such as the impact of assembly on the use of atomizing devices.

[0004] In one embodiment, a press-fit fixture is provided for assembling an atomizing device, the atomizing device including a liquid storage tank and a liquid guide tube, the liquid storage tank having an installation position, and the press-fit fixture comprising:

[0005] The mounting base is used to position the liquid storage tank; a support limiting part is provided on the side of the mounting base facing the liquid storage tank, and the support limiting part is used to support the liquid guide tube so that the liquid guide tube is limited to the mounting position relative to the liquid storage tank;

[0006] The pressing component, acting on both sides opposite to the liquid storage tank, presses the liquid guide tube into the preset position of the mounting location.

[0007] In some embodiments, the support limiting portion is provided with a receiving groove for accommodating the liquid guide tube, and the receiving groove is adapted to the outer peripheral shape of the liquid guide tube so that the liquid guide tube is installed on the mounting position along a direction perpendicular to the horizontal plane of the mounting position.

[0008] In some embodiments, the mounting base further includes a limiting part, which protrudes from the bottom of the receiving groove. The liquid guide tube has a notch on one side facing the receiving groove. The limiting part cooperates with the notch to limit the liquid guide tube from rotating circumferentially.

[0009] In some embodiments, the support limiting part is further provided with an observation port corresponding to the position of the receiving groove. The observation port passes through the side wall of the receiving groove and is connected to the receiving groove; and the limiting part is disposed opposite to the observation port.

[0010] In some embodiments, the liquid storage tank includes a tank body and a puncture portion. The tank body includes a liquid storage cavity, the mounting position is disposed in the liquid storage cavity, the puncture portion is disposed in the liquid storage cavity and located on the mounting position, the liquid guide tube is sleeved on the puncture portion, and the end of the puncture portion extends outside the liquid guide tube.

[0011] The bottom of the receiving groove is also provided with a first clearance groove; the piercing part is inserted between the receiving groove and the first clearance groove.

[0012] In some embodiments, the mounting base includes a fixing part and a positioning part, and the end of the reservoir body is sleeved on at least a portion of the positioning part. The inner contour of the end of the reservoir body is adapted to the outer peripheral shape of the positioning part so that the liquid storage reservoir is positioned on the mounting base.

[0013] In some embodiments, the supporting and limiting portion protrudes into the liquid storage cavity; when the liquid guide tube is pressed into the preset position of the mounting position, the liquid guide tube and the side wall of the liquid storage cavity abut against the surface of the positioning portion.

[0014] In some embodiments, the pressing member includes a pressing part and an operating part, the operating part being disposed on the opposite side of the pressing part pressing the liquid storage tank; the operating part drives the pressing part to move closer to or away from the liquid storage tank.

[0015] In some embodiments, the press-fit fixture further includes a base plate on which the mounting base is detachably disposed.

[0016] An assembly device is provided, including a host and a pressing fixture as described in any of the foregoing embodiments. The pressing fixture is mounted on the host, and the host drives the pressing component to move closer to or away from the mounting base to assemble the liquid guide tube to a preset position of the mounting position.

[0017] According to the press-fit fixture and assembly equipment of the above embodiments, by setting the mounting base and the supporting limiting part, the setting positions of the liquid storage tank and the liquid guide tube can be defined respectively, thereby defining the relative position between the two and improving the assembly accuracy of the liquid guide tube and the liquid storage tank. By using the pressing component, the force can be applied to the liquid storage tank evenly, improving the assembly efficiency and yield. At the same time, the operational difficulty in pressing the liquid storage tank can be reduced by adjusting the outer contour of the pressing component. Attached Figure Description

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0027] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] like Figures 1 to 5 As shown, this application constructs a press-fit fixture 1, which can be used for the assembly of an atomizing device. The atomizing device may include a liquid storage tank 3 and a liquid guide tube 2. The liquid storage tank 3 is provided with an installation position, and the liquid guide tube 2 can be assembled to the installation position.

[0030] The press-fit fixture 1 includes a mounting base 10 and a pressing component 20. The mounting base 10 has a supporting and limiting portion 13 on the side facing the liquid storage tank 3. The mounting base 10 can support and position the liquid storage tank 3. The supporting and limiting portion 13 can support and place the liquid guide tube 2, so that the heat conduction tube 2 is limited to the mounting position relative to the liquid storage tank 3. The pressing component 20 and the mounting base 10 act on opposite sides of the liquid storage tank 3 respectively, assisting in pressing the liquid storage tank 3 to achieve the assembly of the liquid storage tank 3 and the liquid guide tube 2, thereby pressing the liquid guide tube 2 into the preset position of the mounting position.

[0031] It should be understood that the liquid storage chamber 3 has a liquid storage cavity 3011, and the mounting position is located within the liquid storage cavity 3011. The liquid guide tube 2 can be installed into the mounting position within the liquid storage cavity 3011. After the liquid guide tube 2 is installed, the remaining space within the liquid storage cavity 3011 can be filled with a porous structure 4. The porous structure 4 can store atomizing liquid through its porous spaces. During user use, if the atomizing liquid in the liquid storage cavity 3011 is used up, it can be replenished into the liquid storage cavity 3011 through a refill bottle connected to the liquid guide tube 2 for continued use.

[0032] The liquid guide tube 2 needs to be installed in the mounting position within the liquid storage tank 3 so that after the porous structure 4 is filled, the porous structure 4 can fit flush against the outer wall of the liquid guide tube 2. During the replenishment process, the atomizing liquid can smoothly enter the porous structure 4 through the liquid guide tube 2, preventing leakage. If there is an angular error in the assembly of the liquid guide tube 2, and the outer wall of the liquid guide tube 2 does not completely fit flush against the porous structure 4, it may affect the liquid guiding rate of the atomizing liquid and may also cause the atomizing liquid to flow out.

[0033] The "installation position" can be flexibly set according to the shape of the liquid guide tube 2 and the porous structure 4. In the embodiment shown in 5, the position corresponding to the axis M is the installation position of the liquid guide tube 2. If the assembly angle of the liquid guide tube 2 during the assembly process causes an angle between its assembled axis and the axis M, it can be understood that there is an angular error in its assembly.

[0034] This application, by setting an installation base 10 and a support limiting part 13 on one side of it, can respectively limit the setting positions of the liquid storage tank 3 and the liquid guide tube 2, thereby limiting the relative positions between the two. During the assembly process, the liquid guide tube 2 can be installed on the support limiting part 13 first, and then the liquid storage tank 3 can be installed on the installation base 10, thus realizing the assembly of the liquid guide tube 2 and the liquid storage tank 3, so that the liquid guide tube 2 is limited to the installation position relative to the liquid storage tank 3.

[0035] It is important to understand that during the assembly of the liquid storage tank 3 and the liquid guide pipe 2 using the press-fit fixture 1, if the operator manually and continuously presses the liquid storage tank 3 onto the mounting base 10 to achieve mutual pressing between the liquid storage tank 3 and the liquid guide pipe 2, the uneven outer contour of the liquid storage tank 3 may cause operator fatigue. Furthermore, manual pressing makes it difficult to ensure the uniformity of the applied force; if the applied force deviates significantly, there is a potential problem of damaging the liquid storage tank 3.

[0036] By using the pressing component 20, this application can apply force evenly to the liquid storage tank 3, thereby improving assembly efficiency and yield. Furthermore, by adjusting the outer contour of the pressing component 20, the operational difficulty during the pressing process of the liquid storage tank 3 can be reduced.

[0037] like Figure 2 and Figure 4 As shown, in some embodiments, the support limiting part 13 is provided with a receiving groove 131, in which the liquid guide tube 2 can be placed. The receiving groove 131 is adapted to the outer peripheral shape of the liquid guide tube 2 to limit the liquid guide tube 2, so that the liquid guide tube 2 can be installed on the mounting position along the direction of the horizontal plane of the vertical mounting position.

[0038] This application, by providing a receiving groove 131, supports the liquid guiding tube 2 and limits its placement angle on the support limiting part 13. By limiting the angle of the liquid guiding tube 2, the probability of a gap between the outer wall of the liquid guiding tube 2 and the porous structure 4 after assembly can be reduced, thereby reducing the impact on liquid guiding efficiency and improving the consistency of the user experience.

[0039] exist Figure 4 In the illustrated embodiment, the liquid guide tube 2 is generally cylindrical, and the receiving groove 131 is generally cylindrical, with their diameters matching. When the liquid guide tube 2 is placed in the receiving groove 131, the groove wall of the receiving groove 131 can provide uniform support for the liquid guide tube 2 in the circumferential direction, thereby stabilizing the assembly angle of the liquid guide tube 2.

[0040] The depth of the receiving groove 131 can be adapted to the axial length of the liquid guide tube 2, or it can be less than the axial length of the liquid guide tube 2.

[0041] In some embodiments, the cross-sectional shape of the receiving groove 131 may not be consistent with that of the liquid guide tube 2. For example, for Figure 4 The circular tubular liquid guide tube 2 shown can also be provided in a square groove shape, with the receiving groove 131 also being square. In this embodiment, the four walls of the square groove can also provide uniform support for the liquid guide tube 2 in the circumferential direction.

[0042] like Figure 2 and Figure 4 As shown, in some embodiments, the mounting base 10 further includes a limiting part 14, which protrudes from the bottom of the receiving groove 131. The liquid guide tube 2 has a notch 201 on the side facing the receiving groove 131, and the limiting part 14 can cooperate with the notch 201 to limit the liquid guide tube 2 circumferentially and prevent the liquid guide tube 2 from rotating along its circumference.

[0043] like Figure 6As shown, it should be understood that after the porous structure 4 is assembled in the liquid storage chamber 3, the porous structure 4 can also define an atomizing chamber 3012, which can accommodate the atomizing components (heating element, etc.) of the atomizing device. The atomizing chamber 3012 is located within the liquid storage chamber 3011. The atomizing device can also include an atomizing tube 5, which is disposed within the atomizing chamber 3012. Its tube wall is in contact with the side wall of the atomizing chamber 3012 defined by the porous structure 4, and is provided with a liquid inlet 501. During the user's use of the atomizing device, the atomizing liquid in the porous structure 4 can enter the atomizing chamber 3012 through the liquid inlet 501 and be heated and atomized by the atomizing components within the atomizing chamber 3012.

[0044] The liquid guide tube 2 can also be defined by liquid guide holes 202. During the replenishment process, the atomized liquid in the replenishment bottle can enter the storage chamber 3011 through the hollow channel of the liquid guide tube 2 and the liquid guide holes 202. Since the position of the atomizing chamber 3012 within the storage chamber 3011 is relatively fixed, the replenishment speed can be increased by adjusting the number and position of the liquid guide holes 202 to prioritize replenishment to the side closer to the atomizing chamber 3012. For example, in Figure 6 In the embodiment shown, there is a liquid guiding hole 202, which is arranged opposite to the liquid inlet hole 501 of the atomizing tube 5.

[0045] This application, by providing a limiting part 14, can restrict the circumferential angle of the liquid guide tube 2 within the liquid storage chamber 3011. That is, the limiting part 14 controls the relative position of the liquid guide hole 202 within the liquid storage chamber 3011, ensuring that at least one liquid guide hole 202 faces the atomizing chamber 3012 within the liquid storage chamber 3011, thereby improving liquid replenishment efficiency. During production, this improves the consistency of the relative position of the liquid guide hole 202 within the liquid storage chamber 3011 in different atomizing devices, thereby improving the consistency of liquid guiding efficiency across different atomizing devices, reducing product defect rates, and increasing assembly efficiency.

[0046] In some other alternative embodiments, the limiting part 14 can also be configured as a groove, and the end of the liquid guide tube 2 can also be provided with a protrusion. When the liquid guide tube 2 is placed in the receiving groove 131, the protrusion at the end of the liquid guide tube 2 can be located in the groove, which can also achieve a circumferential limiting effect.

[0047] In some alternative embodiments, the limiting part 14 can also be disposed on the side wall of the receiving groove 131. For example, the limiting part 14 can be block-shaped or longitudinally elongated strip-shaped and disposed on the side wall of the receiving groove 131. A corresponding elongated groove can be disposed on the side wall of the liquid guide tube 2. When the liquid guide tube 2 is placed in the receiving groove 131, the limiting part 14 can be movably disposed along the elongated groove. The limiting part 14, in cooperation with the elongated groove, can also play a role in limiting the circumferential movement of the liquid guide tube 2 and preventing it from rotating. The limiting part 14 is a longitudinally elongated groove disposed on the side wall, and the corresponding protrusion structure disposed on the side wall of the liquid guide tube 2 is similar, and will not be described again here.

[0048] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 10 further includes a fixing part 11 and a positioning part 12. The positioning part 12 is disposed between the fixing part 11 and the support limiting part 13, and is used to position the liquid storage tank 3. The fixing part 11 can serve as a base and increase the working height.

[0049] During the assembly process, the liquid guide tube 2 can be placed in the receiving groove 131 of the support limiting part 13 first, and then the liquid storage tank 3 can be fastened on the positioning part 12, thereby realizing that the liquid guide tube 2 is limited to the installation position in the liquid storage tank 3.

[0050] like Figure 3 and Figure 5 As shown, one end of the liquid storage chamber 3 is open. By providing a sealing structure at the open end of the liquid storage chamber 3, the liquid storage cavity 3011 can be sealed. During the assembly of the liquid guide tube 2, the open end of the liquid storage chamber 3 is not yet sealed. Therefore, the outer peripheral shape of the positioning part 12 can be adapted to the inner peripheral shape of the open end of the liquid storage chamber 3, thereby limiting the position of the liquid storage chamber 3.

[0051] Now defined in Figure 4 and Figure 5 In the embodiment shown, the support limiting part 13 is located on the top side of the positioning part 12, and the fixing part 11 is located on the bottom side of the positioning part 12.

[0052] like Figure 5 and Figure 6 As shown, in some embodiments, the liquid storage chamber 3 may also define an airflow detection chamber 3013 for housing structures such as airflow sensors of the atomizing device to detect the user's inhalation. The airflow detection chamber 3013 is located on one side of the liquid storage chamber 3011 and is open at the bottom before the liquid storage chamber 3 is assembled. When the bottom of the liquid storage chamber 3 is sealed, the liquid storage chamber 3 and the airflow detection chamber 3013 are relatively closed.

[0053] Therefore, as Figure 4 and Figure 5As shown, in some embodiments, the sidewall dimension of the liquid storage cavity 3011 is smaller than the inner circumferential dimension of the bottom end of the liquid storage tank 3. Correspondingly, the outer circumferential dimension of the support limiting part 13 is smaller than the outer circumferential dimension of the positioning part 12. The outer circumferential dimension of the support limiting part 13 is adapted to the inner circumferential dimension of the liquid storage cavity 3011. When the liquid storage tank 3 is installed on the positioning part 12, the inner circumference of the bottom end of the liquid storage tank 3 and the outer circumferential side of the positioning part 12 mutually limit each other, and the support limiting part 13 protrudes into the liquid storage cavity 3011, and the outer circumferential side of the support limiting part 13 can mutually limit each other with the inner wall of the liquid storage tank 3011.

[0054] This configuration allows the positioning part 12 to support and limit the liquid storage tank 3, while the support and limiting part 13 can also limit the liquid storage tank 3 to a certain extent. That is, it can further improve the assembly accuracy between the liquid guide tube 2 and the liquid storage tank 3.

[0055] exist Figure 2 and Figure 4 In the illustrated embodiment, the positioning part 12 can be approximately disc-shaped (flattened columnar). The liquid storage tank 3 can be installed on the positioning part 12 by means of pressing or other methods. The support and limiting part 13 can be provided on its top wall. When the liquid storage tank 3 is installed on the mounting base 10, the bottom end of the liquid storage tank 3 surrounds the positioning part 12, and the support and limiting part 13 is located within the liquid storage cavity 3011. The support and limiting part 13 can also be approximately disc-shaped (flattened columnar), and its horizontal cross-sectional shape can be adapted to the contour of the liquid storage cavity 3011 in the horizontal cross-section of the liquid storage tank 3.

[0056] like Figure 5 As shown, the depth of the receiving groove 131 is adapted to the thickness of the disc-shaped support and limiting portion 13. The bottom end of the receiving groove 131 is at least partially blocked by the positioning portion 12 to provide axial support and limiting for the liquid guide tube 2. When the liquid guide tube 2 is pressed into the preset position of the installation position, the liquid guide tube 2 and the side wall defining the liquid storage cavity 3011 can respectively abut against the surface of the top end of the positioning portion 12.

[0057] This setup clearly reminds operators whether the assembly is in place. During assembly, the pressing component 20 is pressed down until it cannot move. At this point, the bottom part of the side wall of the liquid storage chamber 3011 of the liquid storage tank 3 abuts against the top wall of the positioning part 12, preventing the liquid storage tank 3 from moving further down. Simultaneously, the bottom part of the liquid guide pipe 2 abuts against the top wall of the positioning part 12, and the top part abuts against the top of the liquid storage tank 3, thus positioning the liquid guide pipe 2 in its installation position.

[0058] It should be understood that the depth of the receiving groove 131 can be flexibly adjusted based on the relative dimensions of the liquid guide tube 2 and the liquid storage tank 3. In some other optional embodiments, when the liquid guide tube 2 is assembled to the mounting position and the bottom end of the liquid guide tube 2 is located on one side of the bottom end of the side wall of the liquid storage cavity 3011, the depth of the receiving groove 131 can also be set to be greater than or less than the thickness of the supporting limiting part 13, so as to ensure that when the liquid storage tank 3 is pressed into place on the positioning part 12 (when the bottom end of the side wall of the liquid storage cavity 3011 abuts against the top wall of the positioning part 12), the liquid guide tube 2 in the receiving groove 131 is located at the mounting position.

[0059] In some other alternative embodiments, the horizontal cross-sectional shape of the support limiting part 13 may also differ to some extent from the contour of the liquid storage cavity 3011 in the horizontal cross-section of the liquid storage tank 3. For example, Figure 3 The liquid storage chamber 3011 in the liquid storage tank 3 shown is irregularly shaped, and the horizontal cross-sectional shape of its supporting and limiting part 13 can be set as a cuboid. When at least part of the four side walls of its cuboid shape are in contact with the side walls of the liquid storage chamber 3011, the supporting and limiting part 13 can also play a certain limiting role for the liquid storage tank 3.

[0060] In some other alternative embodiments, the top of the positioning part 12 may also be provided with a mounting groove adapted to the liquid storage tank 3. The inner contour of the mounting groove can be adapted to the outer contour of the bottom end of the liquid storage tank 3. By inserting the liquid storage tank 3 into the mounting groove, the limiting effect of the liquid storage tank 3 can also be achieved.

[0061] like Figure 4 As shown, in some embodiments, the support limiting part 13 may also be provided with an observation port 132, which is located at a position corresponding to the receiving groove 131, for observing the setting angle of the liquid guide tube 2 in the receiving groove 131, so as to efficiently realize the limiting part 14 limiting the liquid guide tube 2.

[0062] Specifically, the observation port 132 is hole-shaped, penetrates the side wall of the receiving groove 131, and is connected to the receiving groove 131.

[0063] The observation port 132 may be provided only at the position corresponding to the limiting part 14. The observation port 132 may also extend along the thickness direction of the supporting limiting part 13 (or the axial direction of the receiving groove 131, or the direction of the axis M), and be adapted to the length of the receiving groove 131 in its axial direction.

[0064] In this embodiment, the observation port 132 extends through the support limiting portion 13 in the extending direction of the axis M, and also extends through the support limiting portion 13 in the radial direction of the receiving groove 131. That is, the observation port 132 occupies part of the radial angle of the receiving groove 131, which in this embodiment is approximately a circular groove with 3 / 4 sidewalls along the circumference.

[0065] Continue reading Figure 4 The limiting part 14 is located inside the receiving groove 131 and is disposed on the top wall of the positioning part 12, that is, on the bottom wall of the circular groove. Furthermore, the limiting part 14 is located in the circumferential direction of the receiving groove 131 at the position where the observation port 132 is located, and is disposed opposite to the observation port 132.

[0066] This configuration not only provides support and limits the liquid guide tube 2, but also allows for observation of its circumferential placement. Operators can place the liquid guide tube 2 more efficiently into the receiving groove 131, and the limiting part 14 is positioned within the notch 201, reducing the possibility of damage due to angle issues.

[0067] In some embodiments, the support limiting portion 13 at the observation port 132 position can also be made of transparent material, so that the observation effect can be achieved without providing a hole. Alternatively, the entire support limiting portion 13 can be made of transparent material.

[0068] In some embodiments, as Figure 2 and Figure 3 As shown, the liquid storage tank 3 may include a tank body 301 and a puncture portion 303. The tank body 301 defines a liquid storage cavity 3011 and an airflow detection cavity 3013. During assembly, the open end of the tank body 301 is fitted onto at least a portion of the positioning portion 12, and the inner contour of its open end is adapted to the outer peripheral shape of the positioning portion 12 to facilitate the positioning of the liquid storage tank 3.

[0069] The puncture part 303 is disposed on the main body 301 and located at the mounting position within the liquid storage cavity 3011, and is longitudinally arranged. When the liquid guide tube 2 is installed at the mounting position, the liquid guide tube 2 is sleeved on the puncture part 303, and the outer diameter of the puncture part 303 is smaller than the inner diameter of the liquid guide tube 2. The puncture part 303 is used to puncture the mouth of the replenishment bottle so that the replenishment bottle and the liquid guide tube 2 can communicate, and the atomized liquid in the replenishment bottle can be replenished into the porous structure 4 in the liquid storage cavity 3011 through the liquid guide tube 2.

[0070] See also Figure 5 and Figure 6 The end (top) of the puncture part 303 connected to the body 301 is adapted to the inner diameter of the liquid guide tube 2. When the liquid guide tube 2 is assembled to the installation position, the end of the liquid guide tube 2 is interference-fitted with the end of the puncture part 303 and the body 301 connected to achieve the initial positioning of the liquid guide tube 2 in the liquid storage cavity 3011.

[0071] If the liquid guide tube 2 is assembled to the mounting position, it can be coaxially arranged with the puncture part 303 (both axes are axis M). If the liquid guide tube 2 is tilted during insertion into the puncture part 303, it may generate excessive interaction force with the puncture part 303, potentially damaging the puncture part 303. If the puncture part 303 is damaged, impurity particles may fall and remain in the liquid storage chamber 3011. During user aspiration, these impurity particles may enter the porous structure 4 and flow with the atomized liquid, affecting the user experience.

[0072] Therefore, this application sets the receiving groove 131 to limit the liquid guide tube 2 on the periphery, and sets the positioning part 12 to limit the liquid storage chamber 3 (chamber body 301 and puncture part 303) on the periphery. This can also reduce the risk of damaging the puncture part 303 during assembly, reduce the potential problem of impurity particles left in the liquid storage chamber 3011, and further ensure the user's experience.

[0073] In some embodiments, the length of the puncture portion 303 is greater than the length of the liquid guide tube 2. Therefore, when the liquid guide tube 2 is assembled into the mounting position, at least a portion of the end of the puncture portion 303 extends outside the liquid guide tube 2.

[0074] like Figure 5 As shown, the bottom of the receiving groove 131 can be further recessed to form a first clearance groove 121. Figure 5 In the illustrated embodiment, the first clearance groove 121 is located at the bottom end of the receiving groove 131, and the two are interconnected and coaxially arranged. The positional relationship between the first clearance groove 121 and the receiving groove 131 can be adapted to the positional relationship between the assembled puncture part 303 and the liquid guide tube 2.

[0075] During assembly, the liquid guide tube 2 can be placed in the receiving groove 131 first. Then, the liquid storage tank 3 is pressed onto the positioning part 12. During the pressing of the liquid storage tank 3, the piercing part 303 of the liquid storage tank 3 can be inserted into the liquid guide tube 2, gradually achieving an interference fit between the two, thereby realizing the assembly of the liquid guide tube 2 and the liquid storage tank 3. After the assembly of the liquid guide tube 2 and the liquid storage tank 3 is completed, the piercing part 303 extending to the outside of the liquid guide tube 2 can be located in the first clearance groove 121.

[0076] In some embodiments, the press-fit fixture 1 may further include a base plate 30, which may be disposed at the bottom end of the mounting base 10 to lower the center of gravity of the press-fit fixture 1 and improve operational stability. The base plate 30 may be detachably connected to the mounting base 10 to facilitate the replacement of different mounting bases 10 for the assembly of the liquid storage tank 3 and the liquid guide tube 2 in different models of atomizing devices.

[0077] like Figure 2 and Figure 3As shown, in some embodiments, the fixing part 11 is generally columnar (or disc-shaped), and its outer peripheral dimension is slightly larger than that of the positioning part 12. At least one mounting groove 111 may be provided on the fixing part 11, and at least one mounting hole 31 may be provided on the base plate 30. The press-fit fixture 1 may also include at least one connector 40. By detachably inserting the connector 40 into the mounting hole 31 and the mounting groove 111, a detachable connection between the mounting base 10 and the base plate 30 is achieved.

[0078] exist Figure 2 and Figure 3 In the illustrated embodiment, there are two assembly slots 111, assembly holes 31, and connectors 40 to improve assembly stability. The connector 40 can be a bolt or similar material, and is not specifically limited here.

[0079] In some other alternative embodiments, the mounting base 10 and the base plate 30 can also be detachably connected by means of a snap-fit ​​structure. Alternatively, a sliding connection can be achieved by means of a corresponding slide groove, guide rail, or other structure.

[0080] In some other alternative embodiments, the fixing part 11 may not be provided, and the assembly groove 111 may be provided on the positioning part 12. The mounting base 10 and the base plate 30 can be disassembled and assembled by the positioning part 12 and the base plate 30.

[0081] like Figures 1 to 5 As shown, in some embodiments, the pressing member 20 may include a pressing part 21 and an operating part 22. The pressing part 21 is used to contact the liquid storage tank 3 and apply a uniform force to it. The operating part 22 is disposed on the opposite side of the pressing part 21 pressing the liquid storage tank 3; that is, the pressing part 21 is located on both sides of the operating part 22 opposite to the liquid storage tank 3. The operating part 22 is used by an operator to apply force to the pressing member 20 to drive the pressing part 21 closer to or further away from the liquid storage tank 3.

[0082] By providing the operating section 22, the position where the operator applies force can be limited, reducing the problem of uneven force application. By providing the pressing section 21, the force can be transmitted evenly to the liquid storage tank 3.

[0083] It should be understood that applying force to the operating unit 22 can be achieved by the operator manually pressing the operating unit 22, by using auxiliary tools such as a hand pump, or by electric drive through a guide rail and motor, etc., without specific limitations.

[0084] Therefore, the specific structure of the operating unit 22 can be flexibly set according to the specific method of applying force, and is not specifically limited here. For example, if it is achieved by manual pressing by the operator, it can be set to a structure that is easy for the operator to grip and press. If it is achieved by auxiliary tools such as hand-held presses, it can be set to a structure that is easy to connect to auxiliary tools such as hand-held presses. If it is achieved by setting a guide rail and a motor, it can be set to a structure that is easy to be movably installed on the guide rail.

[0085] In some embodiments, the pressing part 21 is used on the side that contacts the liquid storage tank 3, and its outer contour is adapted to the contour of the corresponding side end (top) of the liquid storage tank 3, so as to further uniformly apply force and achieve a stable pressing effect.

[0086] like Figure 2 As shown, the top of the liquid storage tank 3's main body 301 is also provided with a protrusion 302. (See also...) Figure 3 and Figure 5 The pressing part 21 has a second clearance groove 211 on the side opposite to the operating part 22. When the pressing part 20 is pressed onto the liquid storage tank 3, the protrusion 302 is located in the second clearance groove 211. The second clearance groove 211 can reduce the unevenness of the applied force and limit the position of the pressing part 20.

[0087] It should be understood that the fixing part 11, positioning part 12, support limiting part 13, and limiting part 14 in the mounting base 10 can be integrally formed or fixed to each other by connection structures such as bolts; no specific limitation is made here. The pressing part 21 of the pressing part 20 is similar to the operating part 22.

[0088] This application also provides an assembly device, which may include a main unit and the pressing fixture 1 in any of the foregoing embodiments, to assemble the liquid storage tank 3 and the liquid guide tube 2 in the atomizing device. The pressing fixture 1 can be mounted on the main unit, which is used to drive the pressing component 20 to move closer to or away from the mounting base 10 to assemble the liquid guide tube 2 into a preset position on the mounting site.

[0089] It should be understood that the host can be driven by various methods such as manual pump, motor rail, and manual screw structure, and no specific limitation is made here.

[0090] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
